研究设计：横断面设计。目的：研究复发性腰痛（LBP）缓解期患者和健康参与者在以下下肢运动期间腰多裂肌（LM）厚度的差异：(1)主动直腿抬高（ASLR），(2)屈卧主动直腿抬高（CLR），(3)俯卧直腿抬高（PSLR）。背景：ASLR， CLR和PSLR在临床上用于挑战腰痛患者躯干肌肉控制脊柱运动的能力，并且认为LM活动降低与该人群脊柱控制改变有关。然而，尚不清楚在这些任务中，健康个体和复发性腰痛患者在症状缓解期间的LM行为是否不同。方法：本研究使用超声成像技术测量复发性腰痛患者在症状缓解期间和健康参与者在ASLR、CLR和PSLR任务期间L4-5和L5-S1水平的横指LM百分比厚度变化。结果：在PSLR任务中，复发性腰痛组的LM百分比厚度变化大于健康组(P
STUDY DESIGN: Cross-sectional design.OBJECTIVES: To investigate lumbar multifidus (LM) thickness differences, using ultrasound imaging in people during remission from recurrent low back pain (LBP) and healthy participants, during the following lower extremity movements: (1) active straight leg raise (ASLR), (2) crook-lying active leg raise (CLR), and (3) prone straight leg raise (PSLR).BACKGROUND: ASLR, CLR, and PSLR are used clinically to challenge the ability of the trunk muscles to control spinal motion in people with LBP, and it is believed that decreased LM activity is related to altered spinal control in this population. However, it is unclear whether LM behavior differs between healthy individuals and people with recurrent LBP during symptom remission in such tasks.METHODS: The present study used ultrasound imaging to measure LM percentage thickness change parasagitally at the L4-5 and L5-S1 levels in people with recurrent LBP during symptom remission and in healthy participants, during the ASLR, CLR, and PSLR tasks.RESULTS: LM percentage thickness change was greater in the recurrent LBP group than in healthy participants during the PSLR task (P
